Known Issues
JRE 8u101 is not recognized by Internet Explorer (IE) when using static class ID

When a static class id is used to launch an applet or web start application while using JRE 8u101, users will get an unwanted dialog box stating that they either use the latest JRE or cancel the launch even though they have installed and are using the latest JRE (JRE 8u101). This specific case is only applicable on Windows and IE.

To workaround this issue, users can do one of the following two things:
  • Hit launch with the latest version (8u101) and ignore the warning.
  • Install JRE 8u102 instead of JRE 8u101 to avoid this issue.
To address this issue, developers can do one of the following two things:
  • Use a dynamic class id instead of static class id.
  • Use java_version when using an HTML applet or a JNLP descriptor when using JNLP.

Java Expiration Date

The JRE expires whenever a new release with security vulnerability fixes becomes available. Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. This JRE (version 8u101) will expire with the release of the next critical patch update scheduled for October 19, 2016.

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u101) on November 19, 2016. After either condition is met (new release becoming available or expiration date reached), Java will provide additional warnings and reminders to users to update to the newer version.
